Table 2 describes the fields that are shown in the show environment status command example.

Table 2 show environment status Command Output Fields 

Field
Description

operating clock count

Physical clock count.

operating VTT count

Physical VTT count.

fan tray fan operation sensor

System fan tray failure status. The failure of the system fan tray is indicated as a minor alarm.

VTT 1, VTT2, and VTT3

Status of the chassis backplane power monitors that are located on the rear of the chassis under the rear cover. Operation of at least two VTTs is required for the system to function properly. A minor system alarm is signaled when one of the three VTTs fails. A major alarm is signaled when two or more VTTs fail and the supervisor engine is accessible through the console port.

clock # clock-inuse

Clock status. Failure of either clock is considered to be a minor alarm.

power-supply # fan-fail

Fan failure. Fan failures on either or both (if any) power supplies are considered minor alarms.

Usage Guidelines

If you specify slot, the information is displayed for the specified slot. If you specify all, the information for all slots using the crossbar fabric is displayed. If you do not specify slot or all, the display is the same as if you entered all.

To display all the related crossbar fabric information, enter the show fabric command without keywords.

A fabric channel is each connection between a module and the crossbar fabric module. Each module can have zero, one, or two fabric channels. The more fabric channels that a module has, the more overall bandwidth is available to the module.

The following errors are associated with the crossbar fabrics:

Synchronization errors—General errors are the most common types of errors.

Heartbeat errors—The supervisor engine sends out periodic heartbeat packets to each module using the crossbar fabric. If any of these modules or the crossbar fabric fail to detect heartbeat packets for a period of time, this error is reported.

CRC errors—All packets crossing the crossbar fabric are CRC protected. If any of the ASICs between a module and the crossbar fabric module detect a CRC error, this error is reported.

The three types of fabric switching modes are as follows:

Bus—Packets that travel across the traditional backplane and that are shared by all modules to be switched by the supervisor engine. Modules without the crossbar fabric connectors are restricted to this mode. The 48-port 10/100TX RJ-45 module is an example of this module type.

Crossbar—Packets with headers only that travel across the traditional backplane to be switched by the supervisor engine and that travel across the crossbar fabric. The 16-port Gigabit Ethernet GBIC switching module is an example of this module type.

dCEF—Packets that are switched by the module and that travel across the crossbar fabric. The 16-port Gigabit Ethernet GBIC switching module and the 16-port Gigabit Ethernet module are examples of this module type. The 16-port Gigabit Ethernet GBIC switching module can be in any of these three modes, but the 16-port Gigabit Ethernet module can only be in dCEF mode.

The threshold information is shown only when you enter the no fabric switching-mode allow truncated command.

In the show fabric switching-mode command output, the possible global switching modes are as follows:

Flow-through (Bus)—Mode that the switch uses for traffic between nonfabric-enabled modules and for traffic between a nonfabric-enabled module and a fabric-enabled module. In this mode, all traffic passes between the local bus and the supervisor engine bus.

Truncated—Mode that the switch uses for traffic between fabric-enabled modules when both fabric-enabled and nonfabric-enabled modules are installed. In this mode, the switch sends a truncated version of the traffic (the first 64 bytes of the frame) over the switch fabric channel.

Compact—Mode that the switch uses for all traffic when only fabric-enabled modules are installed. In this mode, a compact version of the DBus header is forwarded over the switch fabric channel, which provides the best possible performance.

Usage Guidelines

Statistics are collected on a per-VLAN basis for Layer 2-switched packets and Layer 3-switched packets. Statistics are available for both unicast and multicast traffic. The Layer 3-switched packet counts are available for both ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.

In some cases, you might see a difference in the duplex mode that is displayed between the show interfaces (virtual switch) command and the show running-config switch (virtual switch) command. In this case, the duplex mode that is displayed in the show interfaces (virtual switch) command is the actual duplex mode that the interface is running. The show interfaces (virtual switch) command shows the operating mode for an interface, while the show running-config switch (virtual switch) command shows the configured mode for an interface.

If you do not specify an interface, the information for all interfaces is displayed.

The output of the show interfaces GigabitEthernet command displays an extra 4 bytes for every packet that is sent or received. The extra 4 bytes are the Ethernet frame CRC in the input and output byte statistics.

Usage Guidelines

The show interfaces counters command displays the number of all of the packets arriving and includes the number of packets that may be dropped by the interface due to the storm-control settings. To display the total number of dropped packets, you can enter the show interfaces counters storm-control command.

The show interfaces counters storm-control command displays the discard count and the level settings for each mode. The discard count is a total of all three modes.

If you do not enter any keywords, all counters for all modules are displayed.

If you do not specify an interface, the information for all interfaces is displayed.

When you enter the show interfaces interface counters etherchannel command, follow these guidelines:

If interface specifies a physical port, the command displays the message "Etherchnl not enabled on this interface."

If interface is omitted, the command displays the counters for all port channels (in the system) and for their associated physical ports.

If interface specifies a port channel, the command displays the counters for the port channel and all of the physical ports that are associated with it. In addition, when you enter the command specifying the primary aggregator in a Link Aggregation Control Protocol (LACP) port channel with multiple aggregators, the output includes the statistics for all of the aggregators in the port channels and for the ports that are associated with them.

show interfaces transceiver (virtual switch)

To display information about the optical transceivers that have digital optical monitoring (DOM) enabled, use the show interfaces transceiver command in privileged EXEC mode.

show interfaces [interface switch-num/mod/port] transceiver [detail | supported-list | {switch switch-num/mod/port} | threshold table | threshold violations]

Syntax Description

interface

(Optional) Interface type.

switch-num

Switch number; valid values are 1 and 2

/mod

Module number.

/port

Port number.

detail

(Optional) Displays detailed information about the interface transceiver.

supported-list

(Optional) Displays the supported transceivers

switch

(Optional) Specifies the interface.

threshold table

(Optional) Displays information about the interface transceiver alarm and warning threshold table.

threshold violations

(Optional) Displays the interface transceiver threshold information.


Command Default

This command has no default settings.

Command Modes

Usage Guidelines

If you do not specify an interface, the information for all interfaces is displayed. The switch switch-num/mod/port keyword and arguments do not appear if you specify an interface.

After a transceiver is inserted, the software waits approximately 10 seconds before reading the diagnostic monitoring information. If you enter the show interfaces transceiver command before the software has read the diagnostic monitoring information, the following message is displayed:

Waiting for diagnostic monitoring information to settle down.
Please try again after a few seconds.
 
   

Wait a few seconds and reenter the show interfaces transceiver command.

show interfaces trunk [module number | switch switch | vlan vlan]

Syntax Description

module number

(Optional) Specifies the module number; see the "Usage Guidelines" section for valid values.

switch switch

(Optional) Specifies the switch number.

vlan vlan

(Optional) Limits the display of switch port information to the specified VLAN. Range: 1 to 4094.


Command Default

This command has no default settings.

Usage Guidelines

Regardless of the type of supervisor engine you are using, the Catalyst 6500 series switch allocates power to the second supervisor engine slot in anticipation of a redundant supervisor engine configuration. You cannot turn off this function.

If you do not install a second supervisor engine, we recommend that you put the highest power-consuming module into the second supervisor engine slot to get the maximum power utilization.

The Inline power field in the show power output displays the inline power that is consumed by the modules. For example, The following example shows that module 9 has consumed 0.300 A of inline power:

Inline power   #    current
module         9    0.300A

Usage Guidelines

In some cases, you might see a difference in the duplex mode that is displayed between the show interfaces (virtual switch) command and the show running-config switch (virtual switch) command. In this case, the duplex mode that is displayed in the show interfaces (virtual switch) command is the actual duplex mode that the interface is running. The show interfaces (virtual switch) command shows the operating mode for an interface, while the show running-config switch (virtual switch) command shows the configured mode for an interface.

The show running-config switch (virtual switch) command output for an interface might display the duplex mode but no configuration for the speed. This output indicates that the interface speed is configured as auto and that the duplex mode shown becomes the operational setting once the speed is configured to something other than auto. With this configuration, it is possible that the operating duplex mode for that interface does not match the duplex mode that is shown with the show running-config switch (virtual switch) command.

Examples

The following example shows how to display the module and status configuration for all modules on a switch:

Router# show running-config switch 1
Building configuration...
 
   
Current configuration : 8183 bytes

standby port

To defer the activation of a port on the standby chassis during standby recovery, use the standby port virtual switching system (VSS) mode command. To disable port deferral activation, use the no form of this command.

standby port {bringup num duration | delay seconds}

Syntax Description

bringup

Configures the number of ports to be activated per cycle and the waiting time between cycles. Note: You must configure the standby port delay time before you can configure the standby port bringup time.

num

Number of ports to be activated per cycle. Range: 1 to 100. Default: 1.

duration

Period of time in seconds between cycles. Range: 1 to 10. Default: 1.

delay seconds

Specifies the period in seconds before port activation is performed. Range: 30 to 3600. Default: 0.


Command Default

Port deferral activation is disabled if standby port delay is not configured. If port deferral activation is enabled, the default number of ports activated in one cycle is one and the duration of the cycle is one second.

Command Modes

Virtual switch configuration submode (config-vs-domain)

15.0(1)SY

Support for this command was introduced.


Usage Guidelines


Note We recommend that enter you this command under TAC supervision.



Note You must configure the standby port delay command before you can configure the standby port bringup command.


If the you configure the standby port bringup without configuring the standby port delay, a message is displayed asking you to configure the standby port delay first and then the standby port bringup. If you remove the standby port delay configuration, the standby port bringup is automatically removed.

In default configuration, all ports are activated simultaneously when a failed chassis is restarted as the standby chassis. You can enter the standby port command to defer the activation of ports that are not virtual switch link (VSL) ports and then activate the ports in groups over a period of time.

You can enter the standby port command to defer the activation of ports that are not virtual switch link (VSL) ports and then activate the ports in groups over a period of time. This can help in reducing traffic loss on the standby ports and alleviate the high CPU utilization on the active switch and route processors during system initialization of the standby chassis.

Examples

The following example shows how to configure the period in seconds before port activation is performed:

Router(config)# switch virtual domain 22
Router (config-vs-domain)# standby port delay 400
Router (config-vs-domain)# 
 
   

The following example shows how to configure the bringup delay for a port's activation during a standby recovery:

Router(config)# switch virtual domain 22
Router (config-vs-domain)# standby port bringup 2 30
Router (config-vs-domain)#

15.0(1)SY

Support for this command was introduced.The keyword preempty delay has been removed from this release and all future releases.

15.1(1)SY

Support for location string keyword was introduced.


Usage Guidelines

You must set the virtual domain name and the switch number prior to converting the chassis into a virtual switch. You cannot configure the switch number after the chassis is in virtual switch mode.

When you bring up the virtual switch, the role resolution logic validates that the chassis numbers are different in the two chassis.

When you configure preempt, the switch with the highest priority assumes the active role during role negotiation.

The preempt keyword is not support in any of the SY releases.

Examples

The following example shows how to assign a switch number, configure the virtual switch domain, and save the switch virtual domain name:

Router1(config)# switch virtual domain 100 
Router1(config-vs-domain)# switch 1 priority 20
Router1(config-vs-domain)# switch 1 preempt 12
Router1(config-vs-domain)# switch 1 location standby

Updated output for auto-configuring the standby VSL.

15.0(1)SY

Support for this command was introduced.


Usage Guidelines

For the VSS to operate correctly, the active chassis needs the configuration information for the other end of the VSL link. The switch accept mode virtual command automatically copies the VSL link configuration from the standby chassis onto the active chassis. The updated configuration is automatically saved to the startup configuration file on the active and standby chassis.

The switch accept mode virtual command performs this action only the first time that the chassis come up as a VSS.


Note The standby chassis must be in hot standby state for the switch accept mode virtual command to execute successfully.


There are no no forms of this command.

Examples

The following example shows how to configure a device in the distribution layer as a standalone switch that has a switch number of 1 in Cisco IOS Release 12.2(33)SXI4 or earlier:

Router1# switch accept mode virtual

switch convert mode (virtual switch)

To select the switch mode, use the switch convert mode command in privileged EXEC mode.

Usage Guidelines

You must reboot both switches when you convert a switch to virtual switch mode.

In a VSS, the interface naming convention includes the switch number. For example, you must use switch/module/port to specify a port on a switching module. The switch convert mode virtual command converts the configuration file to use the VSS naming convention, and saves a backup copy of the file in the RP bootflash.


Note After you confirm the command (by entering yes at the prompt), the switch converts the configuration file and restarts both chassis. After the restart, the chassis is in virtual switch mode. From this point on, you must specify interfaces with three identifiers (switch/module/port).


There are no no forms of this command. You have to specify stand-alone or virtual mode.

You can enter the switch convert mode virtual command only after the standby switch is fully operational (in hot standby mode). If you enter the command before the standby switch is fully operational, a message is displayed telling you to try again later.


Note If you have configured your config-register with a value that would skip file parsing during the bootup process, your change to either a standalone or virtual switch will not take place until you reconfigure your config-register. The config-register must be allowed to parse files in order to ensure the conversion from either a standalone or virtual switch.


Examples

The following example shows how to configure a device in the distribution layer as a standalone switch that has a switch number of 1:

Router1# switch convert mode virtual

Usage Guidelines

The switch read switch_num command is available in both standalone and VSS modes.

In a standalone setting, use the switch read switch_num command to read the value of the active or standby SP ROMMON.

In VSS mode, use the switch read switch_num command to read the value of the active or standby switch supervisor engines SP ROMMON. In a system with four supervisor engines, the in-chassis active (ICA) and in-chassis standby (ICS) should already have the same switch number.

Usage Guidelines

The switch set switch_num command is only available in standalone mode. Because the switch set switch_num command is available only while the switch is in standalone mode, both the local and peer supervisor engines SP ROMMON switch numbers should be set to the same value.

The switch set switch_num command sets or changes the SP ROMMON switch number. Currently, you can set the number to 1 or 2.

The switch set switch_num command is used only as part of the shortcut process to bring up VSS by reusing a saved and matched VSS configuration without going through the actual standalone-to-VSS conversion process. We usually recommend that you follow the official supported VSS conversion process.

Examples

This example shows how to set the active SP ROMMON to 2:

Router# switch set switch_num 2 local

Usage Guidelines

When you enter the switch virtual domain command, you enter the virtual switch domain configuration submode, and the prompt changes to Router1(config-vs-domain)#. Within the virtual switch domain configuration submode, the following commands are available:

default—Sets a command to its defaults

exit—Exits the virtual-switch-domain-mode and returns to the global configuration mode.

no—Negates a command or set its defaults

switch num—Assigns the switch number. See the switch (virtual switch) command for additional information.

You must configure the same virtual switch domain number on both chassis of the virtual switch. The virtual switch domain is a number between 1 and 255, and must be unique for each virtual switch in your network.


Note The domain identification takes effect only after you enter the switch convert mode virtual command.



Note The switch number is not stored in the startup or running configuration, because both chassis use the same configuration file (but must not have the same switch number).


Examples

The following example shows how to configure the virtual switch number and virtual switch domain on two switches:

Router1(config)# switch virtual domain 100 
Router1(config-vs-domain)# switch 1 
Router1(config-vs-domain)# exit 
Router2(config)# switch virtual domain 100 
Router2(config-vs-domain)# switch 2
